Web22 Apr 2014 · With the temperature of an oxy-acetylene flame more than 3000 o F degrees hotter than the 1100 to 1500 o F required for brazing, technicians need to hold the torch farther away so as not to melt the base material (copper melts at 1981 o F). Also, they must continuously move the torch around the diameter of the pipe to evenly distribute the heat ... Web17 Aug 2024 · Air-acetylene produces a flame temperature of around 4000° F (2200° C). This is hot enough to solder aluminum work glass, repair radiators and braze plumbing fixtures. It is not hot enough to weld steel. When acetylene is burned in pure oxygen, the flame temperature may be as high as 5730° F (3166° C). Web10 Apr 2024 · Acetylene is a mixture of hydrogen and carbon in the ratio of 24 parts carbon, and 2 parts of hydrogen--92.3 percent carbon and 7.7 percent hydrogen.
